Hair Follicle Drug Testing - Diana, TX

What it is, How it works

Hair analysis has become recognized as an effective method for identifying substance and alcohol consumption. Hair can archive long-term evidence of drug and alcohol use by capturing biomarkers within the strands of hair as they grow. When sampled near the scalp, hair can offer a detection timeframe for substances of up to around three months. The process of obtaining hair is straightforward, the chances for tampering are low, and it’s convenient to transport.

A hair specimen measuring 1.5 inches with roughly 200 strands (approximately the width of a #2 pencil), cut close to the scalp, yields 100mg of hair, the preferred quantity for analysis and validation. For tests involving EtG, additional substances, or panels beyond 10, 150mg of hair is needed. Measuring the sample with a jeweler's scale is advisable. In cases where scalp hair is not available, the collection of an equivalent body hair sample is permitted. References to head hair strictly concern scalp hair, while body hair encompasses all other types of hair (facial, armpit, etc.).

Process Overview

The laboratory analysis of a drug test outcome comprises four central phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase where a sample is integrated into the laboratory system. This step ensures that the sample is sealed and transported correctly, a unique LAN (Laboratory Accessioning Number) is assigned, and any extra data entry required by electronic chain of custody systems is completed.

Screening offers a preliminary rapid assessment for drug presence. Although it's an economical method to exclude drug use in most samples, any positive findings from Screening must be substantiated for use in legal proceedings. Samples identified with potential positives require further verification through a distinct confirmation stage.

Should a sample demonstrate potential positivity during Screening, additional hair is sourced from the primary sample for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than other methods (like urine or oral fluid), which explains the complexity of conducting tests on hair samples.

Validation of any favorable Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. To ensure accuracy, all samples preliminarily marked as positive are washed before confirmation. The full laboratory sequence from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists)'s Hair certification and the ISO / IEC 17025 credentials.

Advantages of hair drug testing:

• Extended detection range: Hair drug analysis can recognize drug usage up to 90 days earlier, unlike urine tests which offer a shorter detection period.
• Hard to manipulate: Altering the outcome of a hair drug analysis is nearly impossible, thus the findings are more reliable.
• Offers historical insight: It can illustrate a record of drug consumption over an extended span, rather than just recent activity.

Limitations:

• Cannot detect immediate use: Substances take about 5-7 days post-ingestion to appear in hair.
• Expense: Hair drug assessments are typically more costly than alternative testing techniques.
• Diverse results: Variables such as hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the actual process examines the hair strand, not the follicle beneath the skin.
